Skinnsi Hair Removal — Not getting results even my skin turn black and got acne on my face

I have taken 4 session from skinnsi but i haven't recieved any result on hair reduction. After 2-3, months hair are growing again. At the time of counseling they told me that 90% hair will be reduced but after 4 session I haven't seen atleast 10% of the result.. Apart from that I got acne on face after first session on the face it's ruined my face on my wedding they did not tell me about that or any other side effects. My skin is getting tanned after the session although I was taking all the cares your so called dermat suggested. I don't want to taking 2 session which is left u just want my money back.
